Sensitive mobility measurements by phase analysis

The NanoBrook ZetaPALS from Testa Analytical Solutions is a highly accurate and easy-to-use zeta potential analyser using phase analysis light scattering. 

Based on the principle of phase analysis light scattering (PALS) ­ the Nanobrook ZetaPALS is designed for measuring electrophoretic mobilities. It provides an impressive platform for zeta potential determination of nanoparticles and colloids in water with salt concentrations less than 75 millimolar ionic strength.

This new instrument has been designed to eliminate the shortcomings inherent in some other zeta potential instruments. Using the PALS configuration, the Nanobrook ZetaPALS can be used to measure mobilities up to 3 orders of magnitude lower than with a conventional laser Doppler electrophoresis system. It measures complete electrophoretic mobility distributions in just seconds.

The cell configuration eliminates the electroosmotic effect, therefore no stationary levels, alignment or calibration are required. Using low cost, disposable sample cells, no assembly or maintenance are required and the possibility of sample cross contamination is eliminated. 

The software for the NanoBrook Zeta is simple, yet highly intuitive to operate while maintaining advanced features for scientists looking to undertake more complex experiments.
